Issue when encoding to 60fps

[Selur]

@markuskruzs:
a. does the avisynth preview work properly?
b. does using Vapoursynth instead of Avisynth work?
c. in case avisynth preview works fine with your settings what do you get when calling:

"C:\PROGRA~1\Hybrid\32bit\ffmpeg.exe" -y -loglevel fatal -threads 8 -i "C:\Users\User\AppData\Local\Temp\encodingTempSynthSkript_23_20_53_7410.avs" -an -sn   -vf zscale=rangein=tv:range=tv -pix_fmt yuv420p -vsync 0  -f yuv4mpegpipe - | "C:\PROGRA~1\Hybrid\64bit\NVEncC.exe" --y4m -i - --fps 60.000 --codec h265 --profile main --level auto --sar 1:1 --lookahead 16 --output-depth 8 --vbrhq 801 --max-bitrate 240000 --gop-len 0 --bframes 0 --ref 3 --mv-precision Q-pel --preset default --colormatrix bt709 --keyfile "C:\Users\User\AppData\Local\Temp\thisismylifenow_23_20_53_7410_06.qp" --output "C:\Users\User\AppData\Local\Temp\thisismylifenow_23_20_53_7410_07.265"

inside a WIndows Còmmand Prompt?
